Abstract
This invention provides an automatic sensing and correction feature for each fabric type filter element in a filtering system with a multiplicity of separate filter elements, that operates when the filter develops a leak to take only an individual filter element out of service. This is accomplished inexpensively by a simple flap closure valve array that senses increased fluid flow above a set threshold level and chokes off that flow through the individual defective filter cell.
